IPC: H01J29/54
Filed: 1977-09-21
Abstract: PURPOSE: To redouble the electron beam which is controlled via the controlling means by specifying the shape of the focusing electrode provided between the controlling means and the accelerating means and then covering the electrode with the material featuring a large secondary electron discharge coefficient.  
     CONSTITUTION: Focusing electrode 12 is provided between control electrode 4 and accelerating electrode 9, and conical hole 13 is formed featuring a wide beam incident side against hole 6b of electrode 4. Thus, part of beam 14 hits electrode 12 to discharge secondary electron 14e which is accelerated through electrode 9. The discharge amount of the secondary electron is adversely proportional to cosθ with beam incident angle θ, so the discharge amount becomes subatantially 2 to 3 times with the conical hole. At the same time, electrode 12 is covered with the material featuring a large discharge coefficient of the secondary electron to secure more effect. On the other hand, the area contributing to the light emission of fluorescent substance 10 is decreased due to installation of electrode 12. Thus, the deflecting electrode is provided between electrode 4 and 12, so the area where the beams collide with is increased to enhance the resolution. In this way, a high-luminance picture can be obtained

Filed: 1979-09-05
Abstract: PURPOSE:To prevent a video signal from deteriorating in quality by transmitting a specific code from a transmission side in a synchronizing signal period, by resetting a forecasting circuit, and then by resetting a forecasting circuit at a reception side in the detection period of the specific code. CONSTITUTION:A video signal from input terminal 1 has the synchronizing signal separated by synchronous separating circuit 8 and in the synchronizing signal period, an input to forecasting circuit 6 is set to a constant value by the separated synchronizing signal to reset circuit 6, thereby exercising control so that the output of code converting circuit 5 will be a specific code. At the reception side, word synchronizing circuit 18 detects the specific code sent from the transmission side to attain word synchronization. The output of series-parallel circuit 11 is reversely converted by code reverse converting circuit 12 to restore the same signal of quantizing circuit 4 at the transmission side. Pattern detecting circuit 19, considering specificcode reception to be in the synchronizing period, generates an output resetting forecasting circuit 14 and this output and the output of D/A converting circuit 15 are applied to synchronizing signal adding circuit 16, so that the original composite video signal can be obtained from terminal 20.

Title: Defect detector for stationary power converter
Inventor: TANAKA SHIGERU
IPC: H02M1/084
Filed: 1981-07-22
Abstract: PURPOSE:To enable to open a main power switch while a shortcircuiting current flowing in the switch is small by detecting the fact that the deviation between the detected current value of DC side and the detected current value of AC side becomes larger than the set value and judging a defect. CONSTITUTION:When a switching element S2 is shortcircuited and damaged, a shortcircuiting current flows from the R phase of a power source through  switching elements S1, S2 to the S phase of the power source. At the normal time, the detected AC side value IAC is equal to the detected DC side value IL, and the output of an analog switch AS becomes ''0''. On the other hand, when the shortcircuiting current flows so that epsilon3(=IAC-IL)>0 and exceeds the set deviation value epsilon3*, the switch AS generates an output signal ''1'', and applies an open command through a main power open controller MCC to the main power switch MC. In this manner, the power source can be opened before the current flowing the switch MC becomes large.
